摘要：We documented the distributional status of 27 exotic fish species in the inland waters of the Baja CaliforniaPeninsula, Mexico, based on voucher specimens collected from 122 sites between 1977 and 2010, and on publishedrecords. The species reported here are representatives of genera from the Atlantic drainages of North America (Ictalurus,Ameiurus, Pylodictis, Morone, Lepomis, Pomoxis, Dorosoma, Cyprinella, and Micropterus), Middle America (Poecilia,Gambusia, and Xiphophorus), Eurasia (Cyprinus and Carassius), and Africa (Tilapia and Oreochromis). The familycontaining the highest number of species is Centrarchidae (7 species) followed by Ictaluridae and Poeciliidae (6 specieseach). Four species were determined to be invasive due to their wide distribution and fast dispersal through the Peninsula(Gambusia affinis, Poecilia reticulata, Lepomis cyanellus, and Tilapia sp. cf. zillii). We analyze the impacts of exoticspecies on the native populations of 3 species with problems of conservation: Cyprinodon macularius (endangered),Fundulus lima (endangered), and Gasterosteus aculeatus (vulnerable). Alien fishes have been introduced for a varietyof reasons in Mexico: ornament, sport, aquaculture, biological control, and by accident. In some cases fish introductionswere carried out for more than one reason.
